Hmm, this is what seems to be happenning, and I see that others are reporting the same with different setups, different OS, and laptops vs. desktops as well.
If gremlins are the cause, hopefully than that can be easily found programatically (I hope).
However, the only way to perhaps duplicate it is to play at 4 or 5 gigs until it finally shows up (The Crash), which happens to me twice a week.(8 -10 gigs a week).
Kod, I play at small country venues all the time, a pizza shop, a VFW (town pop. = 1500), a brand new bar, etc. etc., (There are NO big venues in Maine) but the 12 - 15 singers I do have on a given night tend to stay all night and sing all night. And because of hoster and its great program, I am able to run 60 - 80 total songs every night and twice on Thursday and Saturday.
However, my wife runs two shows a week with XP and H4.09D and had maybe one crash last year, due to some conflict with VDJ that has never happened again.
My point is I bought a brand new $1500 laptop (top of the line with a top of the line dedicated video card) with nothing on it except VDJ and Hoster 5.07 now 5.08b1, and it tends to crash every 2 or 3 hundred singers, on average. (maybe a windows 7 thing).
My other programs with this same laptop play all videos fine, even karaoke files which it isn't even intended for, w/o problem.

5.08 has run better for me than 5.07 & I didn't have any crashes the last 4 gigs, running BA, and decided it only happened when I also used Tempo & BA together. Tonight I didn't run anything, not BA, no key change & no other programs (I never run anti-virus). Half way through a 4hour show, it just crashed
, after a song stopped, for absolutelly no reason at all
. Restarted Hoster & never happened again.
